    Physics predictions?

    For the rocket question where we had to find the mass of a planet using conservation of energy, do we equate the change in kinetic energy with the change in gravitational potential energy? so 1/2mv^2 = GMm/r (m= mass of rocket, M= mass of planet)

    Physics predictions?

    Also for the last question about testing whether the hypothesis was true, you had to say that the gravitational force of attraction was insignificant to account for the centripetal force since it was too small, right? By comparing GMm/r^2 and mv^2/r

    will 90 raw mark be scaled down?

    Hopefully it's not as hard as 3u or 4u

    there's no way wtf, what's the point of getting 90 raw mark then

    Can 65% raw mark for ext 1 math this year scale to e4?

    Please I really need to get in my course 😭😭

    guys was this the answer to 14)a)?

    But how come there's horizontal asymptotes when y can be any value?

    Maybe I'm wrong, but didn't B and C have horizontal asymptotes, so it couldn't be the answer? Because since y can have any value, and also sin(y) ranges from -1 to 1, so dy/dx has to range from 0 to 2

    Oh I got D for that one

    Wait what was the question again

    But honestly tho those last few questions were pretty hard
  14. J

    What do you guys think of the Ext 2 Math scaling this year? Would it be better than previous years?

    That hard af test got me contemplating my life choices. Or am I just bad lmao

    Can i get 90+ atar with these results?

    Thanks for the insight, I was wondering if I can sort of neglect English, and be content that I can get at least band 3 in it, given that I ace my other subjects? I am pretty confident that if I devote most of my time to my other subjects, I can get band 6s for 3U and 4U and Chinese. But then...
